New when it le desired impart-hoolimovement to "the drive Wheels, the clutch hloole Siero moved into engagement with the adjacent feces of the ringe 36. The engagement of these clutch blocks the rings `will hold toe plates eteionery and thus allow the pinione B2 to revolve under the Iaction of the pinione Si on drive shaft Bil lihe movement of 'these @inf v'eofriloination with o iframe, of mounted theremo2 Castings secured to 'the drive Wheels and having internal gee. e,

The clutch blocks nio] begehii'ted by the lever 53 either into engagement with the rings 36 or the gears 28 and when they are shifted hy this lever the tractor 'will he moved either straight ahead or straight to the rear. The lever 5l may he. shifted however independently of the lever 52 and thus one of the Wheel-she caused to revolve in a forward direction While the other revolves in a rearward direction or one of theeel le vers may he so shifted that the Clutch hloeie will be in neutral positions and one of the Wheels will stond still While Vthe o'zher volvee.
